4LIQUID-FUEL BURNER-l Application inea May` 2s, y1925. fseriai No. 33,334. s

To all cof/,0m t may concern.' 4 y Be it known that I, WILLIAM C. H OMAN, 'a citizen Vof the United States, residlng at Meriden, in the county ofNew Haven and i State'of Connecticut, have invented anIm-l provei'nent in Liquid-Fuel Burners, ofwhich the following is a specification.

I'Ieretofore among other features liquid fuel burners have been constructed to include a casingor shell, and a wick holder therein,` adapted to retain a wick, and de@ /vices for raising and lowering the "wick,

holder to a'djustithe wick to yvariousl positions. So far as I am aware, the devices heretofore employed for adjusting the wick to position have comprised various means for engaging the wick holder at one portion thereof. As commonly constructed the wick holders aie made of sheet material, and are tubular in form, and consequently, by en-V gaging one portion only of the wick holder to move the same within the casingthere is a tendency to move the portion of the wick holder directly engaged to a greater extent than other portions thereof. It naturally The object vof my present invention is tor overcome the disadvantages `to which refer# ence has hereinbefore been made, and to provide in a liquid'fuelburner a kwick holder, and devices for actuatingl thei same in such a manner that oppositely disposed portions ofthe wick holder are simultaneously engaged and uniformly moved soas to produce a right line movement Vin all parts of the wick holder, therebyvprev'enting any tendency of the wick holder to wedge inthe casing, and also insuring a uniform projection of the end of the wick beyond the peripheral portion of the casing to effect a resulting uniform flame from all portions of the wick'when the burner is in use, as will be hereinafter more particularly de-` scribed. f i

In the drawing Fig. l is a sectional elevation of a liquid fuel burner made in accordance with my present invention.

holder, andv Fig. 5 is an elevation on a reduced scale,

illustrating the .wick holder and the wick contained therein. i

Byi reference to the drawing. it will be seen that in carrying out the invention V,the

liquid fuel burner made in accordance there-y K with comprises a casing having anouter wall 1 0, and an inner .wall 11. In corresponding positions `as illustrated the outer wall 10ni'ay be provided 'with a rib 12, and the wall 1,1with an internal yrib 13, Valthough the ribs 12 and 13 play no part .in this invention'. At theinner or 4lowerr ends the outer and innerwalls 10 and 11 are suitably interlocked as indicated at 14 to con-l nect these walls .to one another in concentric relationship so as to provide between them an annular A'space 15v fora wickand wick holder as hereinafter described. In a suitable position inthe outer wall'lO, the same is apertured and Yfitted with airing 16; suitably connected to this lringi16 there is a tapped socket 17"; fitting withiny the socket 17 and abutting against the outerface of the ring 16 I employa collar 18. As illustrated, a portion of this collar is adapted to iit within the ring, and thecoll'ar is provided with a shoulderI for engagement with the outer face of the ring. I also employ a plug 19 that is exteriorly screw threaded so as to be turned down' into the socket 17, and

' at one end is provided with a head 20, which may be 4square as indicated, or hexagonal, or.

andby which the shaft and parts connected thereto may be readily turned in either one direction or the other.

The shaft 21 maybe an a. ribbed rod 23, or suitably connected thereto. The ribs on the rod are indicated at 23, i and as will be understood these ribs form' a4 series of extended'or elongated teeth. 'f In a integral part of position in alignment with the ring 16 in the outer wall 10 the inner wall 11 is apertured as indicated at 2st.. In a diametrically opposite position this inner wall 11 is similarly apertured at 25. These apertures 24 and 25 are of such a diameter as to receive and act as bearings for the end portions of the ribbed or toothed rod 23. Extending diametrically across the inner wall 11 there is a sleeve 26, which surrounds and also acts as a bearing` for the ribbed or toothed rod 23. As illustrated, the apertures 24 and 25 in the inner wall 11 may be defined by inwardly extending fianges, and the extremities of the sleeve 26 fitted over and secured to these flanges. 1t will be understood however, that this construction is merely illustrative, and may be made in any other suitable manner. Also as illustrated, the outer portion of the collar 18 and the inner end of the plug 19 may be suitably recessed so as to provide for a packing 27 to surround the shaft 21, and to make a tight joint between the same and these parts.

Between the outer and inner walls 10 and 11 there is a wick holder 28 with a wick 29 carried thereby. VIn oppositely disposed positions the wick holder 28 is slotted as iudicated at rlhese slots extend longitudinally a predetermined distance, and corresponding edges defining like sides of the slots are provided with teeth 31 and 32 forming racks, which are simultaneously engaged by the end portions of the ribbed or toothed rod 23, which` as will be understood act as pinions in engaging the teeth of these racks. The length lof the ribbed or toothed portion of the rod 23 is substantially the same as the diameter of the outer wall 10, so that as clearly shown in Figs. 1 and 2 of the drawingvthe extremities of the ribbed or toothed portion of the rod engage the teeth 31 and 32, as hereinbefore stated.

It will now be understood that as the shaft 21 is turned the teeth 23 engage the teeth 31 and 32 of the wick holder simultaneously, and consequently, there is a corresponding motion imparted at the same time to oppositely disposed sections of the wick holder. This causes ay uniform motion in either direction of the wick holder between the outer and inner walls, and a corresponding motion of the wick, resulting as will be appreciated in the outer end of the wick extending uniformly in all its parts from the outer peripheral portion of the casing. Furthermore, as will also be appreciated this results in preventing the wick holder from any tendency to wedge, and also results in uniform flame from all parts of the wick.

Although forming no part of the invention, the liquid fuel burner as illustrated., may be supported from a supply pipe 33. by which the fuel to be burned is conveyed to the wick. and a bracket 34 extending between the supply pipe and a suitable support 35 or otherwise.

I claim as my invention:
